If a bitmap image
(or a single plane of an image) is displayed, this option can be used to
specify the color to display for the "0" bits in the image.

-display display

This option allows you to specify the server to connect to; see X(7)
.

-fg
color

If a bitmap image (or a single plane of an image) is displayed, this
option can be used to specify the color to display for the "1" bits in
the image.

-geometry geom

This option allows you to specify the size and
position of the window. Typically you will only want to specify the position,
and let the size default to the actual size of the image.

-help

Print out
a short description of the allowable options.

-in file

This option allows
the user to explicitly specify the input file on the command line. If
no input file is given, the standard input is assumed.

-new

This option forces
creation of a new colormap for displaying the image. If the image characteristics
happen to match those of the display, this can get the image on the screen
faster, but at the cost of using a new colormap (which on most displays
will cause other windows to go technicolor).

-noclick

Clicking any button
in the window will terminate the application, unless this option is specified.
Termination can always be achieved by typing 'q', 'Q', or ctrl-c.

-plane number

You can select a single bit plane of the image to display with this option.
Planes are numbered with zero being the least significant bit.

-raw

This
option forces the image to be displayed with whatever color values happen
to currently exist on the screen. This option is mostly useful when undumping
an image back onto the same screen that the image originally came from,
while the original windows are still on the screen, and results in getting
the image on the screen faster.

-rv

If a bitmap image (or a single plane
of an image) is displayed, this option forces the foreground and background
colors to be swapped. This may be needed when displaying a bitmap image
which has the color sense of pixel values "0" and "1" reversed from what
they are on your display.

-scale

Allow the window to be resized, and scale
the image to the size of the window.

-std maptype

This option causes the
image to be displayed using the specified Standard Colormap. The property
name is obtained by converting the type to upper case, prepending "RGB_",
and appending "_MAP". Typical types are "best", "default", and "gray". See
xstdcmap(1)
for one way of creating Standard Colormaps.

-vis vis-type-or-id

This option allows you to specify a particular visual or visual class. The
default is to pick the "best" one. A particular class can be specified:
"StaticGray", "GrayScale", "StaticColor", "PseudoColor", "DirectColor",
or "TrueColor". Or "Match" can be specified, meaning use the same class
as the source image. Alternatively, an exact visual id (specific to the
server) can be specified, either as a hexadecimal number (prefixed with
"0x") or as a decimal number. Finally, "default" can be specified, meaning
to use the same class as the colormap of the root window. Case is not significant
in any of these strings.
